In Michigan, legal tint is measured by VLT — the percentage of light the filmed glass lets through. The numbers below are the darkest tint the law allows at each window position, labeled VLT MAX: install film darker than the listed VLT and the vehicle is out of compliance. Figures are compiled from official Michigan state sources; laws change, so confirm the current statute before you tint.
| Window | Darkest Legal (VLT MAX) | Reflectivity |
|---|---|---|
| Windshield | No film at all except tinted film along the top edge: the material may not extend more than 4 inches from the top of the windshield, or lower than the shade band, whichever is closer to the top — (1)(a) | |
| Front side windows (and sidewings adjacent to / forward of the driver or front passenger) | The same strip rule as the windshield: film only along the top edge, within the same 4-inch / shade-band limit — (1)(a). Michigan sets no percentage for these windows — full-window film is not permitted at any darkness | |
| Rear side windows | Any darkness — no transmittance limit in the statute. The only cap: material creating a total solar reflectance of 35% or more, including silver or gold reflective film, is prohibited — (1)(b) | |
| Rear window | Any darkness, same 35% solar-reflectance cap — (1)(b). MSP guidance adds the practical condition: tinting the rear window is limited to vehicles with outside mirrors on both sides |
How to Read These Numbers
- Windshield: The windshield rule controls the strip at the top of the glass and how far film or a visor band may extend down. Most states allow a non-reflective strip above the manufacturer's AS-1 line.
- Front side windows (and sidewings adjacent to / forward of the driver or front passenger): Front side windows — driver and front passenger — are the most tightly regulated and the ones checked first at a traffic stop or inspection.
- Rear side windows: Rear side windows are usually allowed darker than the fronts, and on SUVs, trucks and vans they are sometimes exempt from the passenger-car limit.
- Rear window: The rear window rule often interacts with side mirrors: darker rear glass typically requires dual outside mirrors.

Michigan Tint Law Questions
What is the darkest legal tint in Michigan?
For front side windows, Michigan allows tint down to The same strip rule as the windshield: film only along the top edge, within the same 4-inch / shade-band limit — (1)(a). Michigan sets no percentage for these windows — full-window film is not permitted at any darkness — the VLT MAX. Rear windows may allow darker film; check the table above for each position.
What happens if my tint is darker than Michigan allows?
Over-dark tint can draw a citation and, in many states, a fix-it order requiring the film to be removed and the vehicle re-inspected. Laws also change — verify the current statute before tinting.
